I'm reading it again now, and hopefully I am not misinterpreting what Rabbi Melamed is quoted as saying. He is saying Jews can go up "if pure." Does that mean after a mikveh immersion? I know that some people will say we are all impure today even regardless of going in a mikveh.... I assumed he would not be saying along those lines, but reading it carefully I'm not sure exactly what Rabbi Melamed is saying here.
